COLLAPSIBLE CHAIR.

' Application filed December 8, 1913.

1/ all whom it may concern Be it known that I, Orro HOLGERSON, a citizen of Denmark, (who has taken out his first naturalization papers for citizenship in the United States of America and intends to take out his final papers as soon as he can,) now residing at Peabody, in the county oi Marion and State of Kansas, have invented certain new and useful Improvemerits in Collapsible Chairs, of which the following is a specification.

This invention relates to improvements in collapsible stools or chairs, the object in view being to provide a structure susceptible of being folded into very compact form for carrying the same or for disposition when not in use.

A. device constructed in accordancewith my invention comprehends a supporting standard to which are connected at one end legs capable of being folded about said standard in spaced relation to each other and at its other end seat supporting arms adapted for folding similarly about the standard into the saaces between the legs aforesaid.

In carrying out the invention it is contemplated to employ anenvelop or bag into which the folded chair may be closed to facilitate carrying of the same, which envelop is adapted to-co6perate with the chair when it is unfolded into operative position to form a back resttherefor.

With the above and other objects in View, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein: I r

Figure 1 is a side elevation of achair constructed in accordance with my invention in extended operative position. Fig. 2 is a rear elevation of the same. Fig. 3 is a view of the chair in collapsed position and showing in d tted lines the position assumed by seat arms in their collapsing movement. Fig. t is a fragmentary plan view of the seat member. Fig. 5 is an enlarged detail view of one of the bracket members carried by the chair standard to which the leg and arm elements are connected. Fig. 6 is a fragmentary View of the chair standard, partly inisection and showing more clearly the locking member for holding the legs in extended position.

cpnstrifict'ed in accordance with my invention, the numeral 1 represents a vertical standard. or post comprising spaced members and to thelower extremity of the same is fixedly secured a bracket2 shown more clearly in Fig. 5 of the drawings. The bracket 2is formed with a plurality oi arms bifurcated at their outer extremities, three of such arms being employed in the actual construction of my device; Pi'votally securedin the bifurcated portions of thearms of the bracket 2 are supporting legs 3, to intermediate pointso'f which are connected one end of cooperating brace members 4, the other end of each brace member being similarly connected to a slidable bracket 5 similar in construction to the bracket 2 liereinbefo're mentioned. In the position shou' 'n in Figs. 1 and'2 of the drawings, the legs8' are held in their extended or operati v'e position bymieans'of the brace members 4 and the bracket'member 5 which is mountfor sliding movement vertically'between the side members of the standard 1. Locking means engaging the bracket member 5 so as to prevent movement of the same and collapsing of the legs 3 is employed and consists of a spring member 6 secured to the standard 1 atone end and having an inwardly projecting extension 7 adjacent its other end and adapted to pass through one side of the standard 1 over the bracket 5. A finger-piece is formed on the spring member to facilitate" disengagement of the locking means when it is desired to collapse the legs. 7 It will be noted tliat the upper end of the standard 1 has fixedly secured thereto a third bracket 2 similar in construction to the brackets Qan'd and said bracket 2 has pivotally connected thereto the seat supporting elements. These elements comprise the rearwardly extending divergent pair of arms 9 and a third a m 10 projecting forwardly of the chair. T he seat member 11 shown most clearly in Fig. 4 is of triangular shape and carries at its rear corners hook members 12 adapted to engage about the headed projections 13 mounted in the free extremities of the rear arms 9. The seat has also at its forward corner a hook or eye 14 adapted to engage over thefree extremity of the seat supporting arm 10 which extremity is notched to insure positive engagement of the eye therewith. It will be obvious that the triangular formation of the seat and particular arrangement of the arms permits said arms to be held in extended operative position by the seat member 11 and upward movement of the arm 10 is limited by the provision of a rearwardly extending arm 15 connected to the arm 10 intermediate of the same and adapted for abutment against the short projection 16 secured to the upper extremity of the standard 1. Not only does the arm 15 and its cooperating member 16 limit upward movement of the arm 10 but it also prevents collapsing or further upward movement of the seat supporting arms when pressure is applied to the seat member 11 as when a person sits thereup n.

Pivotally secured to each of the diverging seat members 9 at their outer extremities and mounted on the pivot members 13 is a back standard 17 adapted to be moved into a vertical position such as shown in Figs. 1 and 2 when the chair is in use and the lower extremity of each of these standards is bent laterally as indicated at 17 so as to cooperate with the under edge of its contiguous seat member 9 to limit the pivotal movement of the standard. The standards 17 aforesaid are adapted to perform the function of a back rest and the envelop or back 18 in which the folded chair is adapted to be carried, is disposed over the standards with the latter projecting into the pocket of the envelop as shown most clearly in Fig. 2 of the drawings. The back rest is, therefore, formed by cooperation of the bag with the upright members 17 and as hereinbefore stated contains a pocket portion which is closed by the flap 19 having suitable fastening members 20 thereon and preferably a strap member 21 is secured to the bag to facilitate carrying of the chair when folded and inclosed therein.

From the foregoing description, it will be understood to collapse the chair compre-c hended by this invention, the locking mem- Gopies of this patent may be obtained for her 6 is withdrawn from engagement with the bracket 5 and grasping one or more of the legs 3 they are forced upwardly about their pivots moving the bracket member 5 in its guiding slot or between the spaced side members of the standard into the full folded position shown in Fig. The seat member 11 is then disengaged from the supporting arms 9 and 10 which are depressed into a position adjacent the standard and lying intermediate the upfolded legs 3. The back rests 17, from which have been previously removed the bag 18 are simultaneously moved on their pivots as shown in dotted lines in Fig. 3 so as to lie parallel with their cooperating seat supporting arm 9. The folded chair is then inserted in the bag 18 along with the flexible seat member 11 and it will be apparent that a very small compact article is provided by this peculiar arrangement of parts.

As shown in Fig. 1 the seat member 11 may comprise a flexible fabric reinforced by leather cross straps 11 so as to prevent distortion or stretching of the material.

Having thus described the invention, what 1 claim as new is:

In a collapsible chair, the combination of a standard, a bracket fixed to the upper portion of the standard, arms pivoted thereto and adapted to be engaged by a flexible seat member, a plate fixed to the upper portion of the standardand extending on an. in cline therefrom, the said plate having an offset portion, and an arm pivoted to one of the seat engaging arms and having a free end adapted to engage the offset portion of said plate for retaining the arm against inward collapse.

In testimony whereof I affix my signature in presence of two witnesses.
